The first analog input is suitable forconnecting a redox combination electrode or a metal/reference electrode. The secondanalog input can be used to connect Pt100 or Pt1000 resistance thermometers.The instrument features two 4-digit 7-segment displays for indicating the temperatureindependentredox-potential process value (red) and the temperature (green). Theinstrument is delivered as standard with the temperature display switched off. A separatetemperature sensor (Pt100 or Pt1000) can be attached to the second analog input, andused to indicate the temperature of the medium being measured and to monitor it througha limit comparator (limt switch), if required. During programming, the displays providecomments on the inputs.A great variety of control tasks can be handled by the various output options (relaycontacts and/or analog outputs). The two relay “make” contacts that are provided on theinstrument as standard can be configured as a limit controller and/or pulse width or pulsefrequency controllers, or as a modulating controller. To obtain analog (continuous)controller outputs, the optional analog outputs must be configured accordingly.All controller outputs can be configured for a P, PI, PD or PID control action.In the entry level version, the instrument provides two relay “make” contacts and one logicoutput (0/5V). Two additional outputs can, according to choice, be fitted as relaychangeover contacts and/or analog outputs (process value output or analog controlleroutput) or as a serial interface (Profibus-DP or Modbus/Jbus protocol).Type 202535 / …/640Block structureKey features❏ Panel-mounting instrument,just 96 x 48 x 110 mm❏ Display in mV❏ 2 relays as standard, freelyprogrammable as limit controller orP, PI, PID, PD controller with pulsewidth/pulse frequency output ormodulating controller❏ 2 electrically isolated analog outputs0(4) — 20 mA / 0(2) — 10 V freelyselectable and scalable for redox❏ 2 logic inputs❏ Monitoring and displaying temperatureof medium is possible❏ Simple, step-by-step calibrationprocedure❏ OPTION: Profibus-DP or serialinterface RS485 / 422 with Modbus/Jbusprotocol❏ Surface-mounting housing toDIN 43 700, front protection IP65.❏ Wall-mounting housing protected to IP6708.04 / 00363906

Setpoints SPr1 andSPr2 can be altered by using themembrane keys.Parameter levelThe controller is adapted to the controlloop at this level. The appropriateparameters appear here, with symbol andvalue.Only those parameters will be indicatedwhich correspond to the configuration ofthe controller (configuration level).Configuration levelThis level is used to adapt the controller tothe control task, or for adaptation of theinputs and outputs.(1) Status indicators (yellow)for outputs 1 to 4(2) Increment key for altering parametersor manual operation of relay K2(3) Decrement key for altering parametersor manual operation of relay K1(4) EXIT key to leavethe levels(5) PGM key for selection of parametersand confirmation of entriesCalibration optionsThe electrode zero point of a redoxcombination electrode is subject tomanufacturing tolerances and variationsdepending on usage.The transmitter offers the feature of usinga step-by-step calibration procedure – the1-point calibration – to make a freshdetermination of the zero point of theelectrode by using a buffer solution or asolution with a known redox potential.The transmitter also offers the facility ofmanually entering or adjusting the zeropoint (as determined by a laboratory, forexample).Additional functions of the JUMOdTRANS Rd 01❏ Programmable response of theprocess value output tounderrange/overrangeOn underrange or overrange, theprocess value output can move to thefollowing operational states:-4%, 0%, 100% or 110% freelyselectableExample: Instrument is programmed to4 — 20 mA corresponding to100 — 500 mVThe instrument can be set up so that, onfalling below 100, the output signal iseither held at 4 mA (0%) or drops to3.84 mA (-4%).

The outputs of the relays K1 andK2 can move to the following(programmable) states on “Hold”:0% Relay de-energized50% output For dynamic controllers,50% of the maximumpulse width or frequencyis produced100% output Relay is energized, ormaximum pulse width /frequencyOutputacceptedThe present outputcontinues to beproduced❏ In “Manual” mode, the relays K1 andK2 are operated manually, by usingthe keys. Either key or switch operationcan be selected, by a setting at theparameter level.Key operation: The relay is switched aslong as the key is pressed (e.g. formanual dosing).Switch operation: The first key strokeswitches the relay on – the secondswitches it off again (toggle action), e.g.for emptying large tanks.08.04 / 00363906

This is used for communicationwith higher-level systems and integrationinto a data network. The transmissionprotocol can be either Profibus-DP orModbus/Jbus.Technical dataInputsAnalog input 1Input resistance ≥ 10 12 ΩInsulation resistance of the referencesystem connection to ground > 10 7 Ωaccording to DIN 19 265For all the usual metal combinationelectrodes or metal/reference electrodes.Analog input 2Resistance thermometer Pt100 orPt 1000, in 2- or 3-wire circuit-50 to +250°CMeasurement display in °C (option °F)Lead compensation, analog input 2The lead resistance can be compensatedin software by a correction of the processvalue.This is not required if the resistancethermometer is connected in a 3-wirecircuit.When a resistance thermometer isconnected in a 2-wire circuit, leadcompensation can be provided by using anexternal compensation resistor.Functional description of logic inputs 1and 2The two standard logic inputs can beoperated by floating contacts (relays) froma PLC, or by switches. The followingfunctions can be selected and assigned:Key inhibit: The PLC or a key switch can beused to lock the keys on the transmitter, toprevent unauthorized entries being made.Setpoint changeover: For comfortableprocess control. As long as the logic inputis not operated, setpoint pair SPr1 andSPr2 is active. If the appropriatelyconfigured logic input is operated, then thesecond setpoint pair is activated.Freeze measurement: The indicatedmeasurement and the process valueoutput no longer change.“Hold”: This function can be used (forinstance, by a supervisory PLC) to put theinstrument into the secure “Hold” state.The response of the controller to “Hold” isas previously defined.“Hold reversed”: The same function asHOLD, but when the logic input is open.Alarm stop: The alarm generation via theconfigured output is prevented, but thealarm LED (e.g. K4) continues to blink as awarning.Reset alarm time: The alarm generation viathe configured output is prevented. Thealarm delay time is set to zero, but isrestarted when the logic input becomesinactive and the start conditions are fulfilledonce more. The alarm LED (e.g. K4)continues to blink as a warning.Range expansion (x10): If only a smallportion of the measurement range is used,it may be advantageous for the transmitterto react to 0 — 10% of the process valueby producing 0 — 100% of the outputsignal.Measurement and control range-1999 to +1999 mVDeviation from characteristic≤ 0.25% per 10 °CAmbient temperature error≤ 0.15% per 10 °CTemperature display-50 to +250°C (option °F)Deviation from characteristic≤ 0.25% of measurement rangeAmbient temperature error≤ 0.1% per 10 °COutputs2 relay outputs, 1 logic output, 1 analogprocess value output or 1 additional relay,and 1 serial interface are available.1.
